In the case of atoms, it has protons, neutrons, and electrons in it, and each of these sub-atomic particles carries a definite mass, although a neutron is chargeless it has a mass. Answer and Explanation: Atomic mass Th...
The calculation of crude prevalence ratios (PRs) revealed that A-bomb survivors had a significantly higher prevalence of hypertension (PR, 1.16; 95% CI, 1.00-1.35) and chronic liver disease (2.20; 1.59-3.06) than controls. After adjusting for covariates (age, sex, body mass index, marital ...

It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Bi-179 (Bismuth, atomic number Z = 83, mass number A = 179). Landolt-Brnstein Homepage Introduction Index 展开 ...
Multiple regression analysis of age, sex, smoking, body mass index, 1-h BG, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and radiation dose also showed that total cholesterol was negatively (RR = 0.872; 95% CI = 0.793-0.958) and radiation dose positively (RR = 1.809...
elements can be found in nature. some atoms of a given element may have different mass numbers. their atomic numbers, however, are the same. these are known as isotopes. isotopes are thus defined as different atoms of the same element with the same atomic number but different mass numbers....
It undergoes reversible crystalline–amorphous structural transformations and flows along the electrified Cu surface, thus mediating the crystalline Cu surface restructuring and mass loss through the interphase layer. The combination of real-time observation and theoretical calculations unveils an amorphization-...

into the seed fibrils during the course of the experiment. However, the very high mass sensitivity of the QCM permits to resolve even the growth rate of this slow growing mutant, and hence we base our analysis of the relative growth rates exclusively on the QCM experiments (Supplementary Fig....
